 When we arrive at the beach, watch the waves breaking on the sand for a few minutes. Find a stick and put it deep into the sand at the highest point the waves reach. Close your eyes and listen to the waves. What does the sound remind you of? What do you smell? Time the waves. How many waves break in a minute? How many seconds pass between the breaking of each wave? Is the amount of time between waves the same each time? Before we leave in the afternoon, check the stick you put in the sand. How far is it from the highest place the waves are breaking now? Other observations: There are 18 animals on our Tidepool Treasure list. How many can you find? For each animal you find, each person in your group must: Identify it, using the Tidepool Treasure drawings, and the Pacific Intertidal Life guidebook. In your journal, record the name of the animal and the location, including the tide zone where it was found. Use the small ruler on the back of the guide book to measure the animal. Record this measurement. Make a large, detailed sketch of the animal. Take notes on the behavior of the animal. How does it protect itself? How does it hide? You get Bonus Points for
Animals or Plants you identify and draw that are not on the Tidepool
Treasure list. There will be prizes for the teams with the best
Journals! How do we get a picture of the whole tidepool ecosystem? This survey will give our class ten or more random samples. Take the string circle and roll it into a ball, then throw it out into the tide pool. Wherever it lands, spread it into a complete circle. Write down a description of the location, including the zone you have hit. Identify and write a list of all the plants and animals contained within the circle. Count how many of each type. Record any interactions you see. Is any animal eating the plants?
